JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 794,259, dated July 11, 1905.

Application filed July 18, 190 Serial No. 217,118. i

To all whom, it ntcty concern.-

Be it known that I, THOMAS H. SYMINGTON, a citizen of the United States of America, and a resident of 706 St. Paul street, city of Baltimore, and State of Maryland, have invented certain new and useful Improvements in Journal-Boxes, of which the following is a specification.

My invention relates to a journal-box of standard type, which is generally known as the Master Oar-Builders journal-box, and has for its object to decrease the quantity of waste and oil necessary for the lubrication of the box. 'I have found by experience that by raising the bottom of the box so as to bring it into close proximity to the axle, and providing it in its center with a longitudinal vertical rib, I can pack the box with about one-third less waste than usual and lubricate the box with much less oil than is usually used, at the same time preventing the waste from being rolled from one side to the other of the box, and thus accomplish entirely satisfactory lubrication of the journal with a large economy. The raising of the bottom of the box enables me to provide external transverse and longitudinal ribs, by which the bottom is greatly strengthened, the internal rib also operating to strengthen the bottom, and this result is accomplished within the limit of size permitted in a standard box.

Referring to the drawings, Figure 1 is a vertical section of my improved journal -box. Fig. 2 is an end elevation, partly in transverse section, of my journal-box.

Referring to the drawings, 1 is the journal; 2, the box surrounding the journal; 8, the shallow bottom; 4, the vertical longitudinal rib located in the center of the bottom and approximately radial of the journal. The rib 4: does not extend the full length of the bottom, but as far as the length of the journal. It does not extend to either end of the bottom, but only at its center portion, thus leaving an unobstructed transverse passage-way at each end of the rib for the passage of oil from one side to the other of the box. At the center of the rib, opposite the head and shoulder of the journal, the rib has its maximum height.

At the forward end, opposite the head of the journal, the rib is lower. This is for the purpose of enabling the center of the rib to be raised up as high as possible toward the bearing-surface of the journal without striking the journal, because when the journal rocks inside of the box the head will sometimes be depressed until it strikes the low part of the rib, and this low part is provided to prevent the high part of the rib from striking the bearing surface of the journal.

5 5 5 are transverse ribs on the exterior of the box, running from side to side thereof, and 6 is a longitudinal rib, also upon the exterior of the box, running from one end to the other thereof. These transverseand longitudinal ribs strengthen the bottom very materially without increasing the Weight and at the same time fill the space between the standard attaching devices for the box, so as to enable the box to be fitted therein, notwithstanding the elevated bottom.

In a particular form of box shown in this application the longitudinal external rib 6 is located in the same vertical plane, which is radial to the axle. With the internal rib 4. Consequently the rib 4 coacts with the rib to strengthen the bottom of the box, and these two ribs, one on each side of the bottom, in conjunction with the transverse ribs, make the bottom of great strength and one able to withstand the forces which in service tend to break it, and they do this with but slight increase in the weight of metal employed in the construction of the box. As a matter of fact, this box is lighter than the standard Master Oar-Builders box and at the same time is stronger.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A journal-box of standard type, having a bottom more closely approaching the journal than heretofore in said type, the bottom being provided with alongitudinal rib approximately radial of the journal and adapted to hold the waste in proper position in the box, said rib extending to within a short distance of the front and rear of the box, leaving a space between the ends of the ribs and the ends of the box.

2. A journal-box of standard type, having a substantially horizontal bottom more closely approaching the journal than heretofore in said type, the bottom being provided on the interior with a longitudinal rib, approximately radial of the journal, said rib being of a length somewhat less than the distance between the head and shoulder of the journal, of the box.

3. A journal-box of standard type having a substantially horizontal bottom more closely approaching the journal than heretofore in said type, the bottom being provided on the interior With a longitudinal rib, approximately radial of the journal and extending a distance less than that between the head and shoulder of the journal, and a longitudinal rib on the exterior of the bottom opposite to the rib on the interior and located in the same plane radial to the journal.

4:. A journal-box of standard type, having a substantially horizontal bottom more closely approaching the journal than heretofore in said THOMAS H. SYMINGTON.
